Cboe Global Markets, Inc. CBOE Moat

Key data

The moat

Cboe owns two things and only one of them is defensible.

The defensible one is the index options franchise. Options on the S&P 500 and on the volatility index are Cboe's own products, listed exclusively on its own exchanges, and an institution hedging equity exposure has no alternative venue for them. That is a product monopoly wrapped in a network effect, because the liquidity in an exclusively listed contract cannot fragment.

The other is exchange operation in multi-listed securities: cash equities and options listed on fourteen or more venues. There, Cboe is one matching engine among many competing on rebates, and there is no moat at all.

What the real moat produces is pricing power on the exclusive contracts, and it shows up in the options segment revenue rising 54% while the share numbers fell.

Widening or narrowing

The two businesses diverge completely.

Equities share fell 340 basis points across ten quarters with almost no interruption. Options share eroded more gently to a low of 29.1% before recovering. Revenue rose regardless, because the exclusive contracts carry a fee nobody competes away.

The equities decline is mostly not Cboe losing to another exchange. Cboe's own off-exchange share rose from 14.9% to 18.8% over the same window, meaning the volume left the lit venues entirely for internalisers. That is an industry-wide shift and it removes revenue from every exchange, Cboe included.

The overrated case. The rising options revenue is the number that carries this company and part of it is volume rather than franchise. Retail options activity has been at records, and a 54% revenue increase during a period when the company's own options share fell is a market growing faster than Cboe's slice of it. If activity normalises, the exclusive contracts still hold and the revenue does not.

On profit pool, Cboe holds the fat slice in index options, where it collects the fee on a product it invented, and a thin contested one everywhere else. Sixty-nine percent of its net transaction and clearing fees settle through a single clearing agency it does not own, which is a dependency rather than an advantage.

The primary moat is widening. The commodity half is not.
